Page 2 Resilient VCStack provides fast failover for uninterrupted network service. High availability features ensure traffic flow continues even during outages. VCStack VCStack delivers a resilient core at a fraction of the cost of a full chassis- based system. You can create a single "virtual chassis" from two physical devices. VCStack provides a highly available system where network resources are spread out across stacked units, reducing the impact should one of the stacked units fail. You can aggregate switch ports on different units, for excellent high availability. Control Plane Prioritization (CPP) Ensure maximal performance and prevent network outages with CPP. CPP prevents the Control Plane from becoming flooded in the event of a network storm or Denial of Service (DoS) attack. Scalable Add more XEMs as your network grows. Add more devices to a VCStack to increase port density and resiliency without increasing management complexity. Our high speed XEMs provide both copper and fiber connectivity, delivering the ultimate in flexibility. XEM options are: • AT-XEM-1XP - 1 x 10GbE (XFP) • AT-XEM-2XP - 2 x 10GbE (XFP) • AT-XEM-12S - 12 x 100/1000BASE-X SFP ports • AT-XEM-12T - 12 x 10/100/1000BASE-T (RJ-45) ports • AT-XEM-STK - Stacking All XEMs provide non-blocking performance. XEMs are ideal for aggregating gigabit to the desktop or for gigabit uplinks from Fast Ethernet switches. Reliable Hot-swappable XEMs, redundant hot-swappable PSUs and replaceable fans ensure no network interruptions during maintenance or reconfiguration. 10GbE expansion modules and hotswappable XFPs provide high-speed, high- capacity fiber uplinks, with the option of either 10Gbps or 20Gbps uplink capacity to the network core. The x900 Layer 3+ switches operate with one PSU - installing a second PSU provides redundancy. Internal PSUs eliminate the need for an external Redundant Power Supply (RPS) that occupies valuable rack space. Built-in redundancy guarantees the continued delivery of essential services. The x900 switches also feature front-to-back cooling, maximising their reliability. High-performing Non-blocking architecture and superior QoS ensure wire-speed delivery of all your critical IPv4 and IPv6 traffic. Ethernet Protected Switched Rings (EPSRingTM) EPSR and 10 GbE modules allow several x900-24X switches to form a protected ring with 50ms failover.This feature is perfect for high performance at the core of enterprise or provider access networks. Wire speed switching The x900 Layer 3+ switches have fully non-blocking switching on all ports, so IPv4 Layer 2 switching and Layer 3 routing occur at wire speed. This is ideal for high-end server deployments, and when aggregating gigabit connections. Aggregation at Layer 2 and Layer 3 A large L3 route table provides support for thousands of IP interfaces, essential when aggregating complex IP networks. Industry-leading Quality of Service (QoS) Comprehensive low-latency wire-speed QoS provides flow-based traffic management with full classification, prioritization, traffic shaping and min/max bandwidth profiles. Enjoy boosted network performance and guaranteed delivery of business-critical Ethernet services and applications. Time-critical services like voice and video applications take precedence over non-essential services like file downloads, maintaining responsiveness of Enterprise applications. Unmatched QoS accuracy is achieved with a bandwidth limit resolution down to 1Kbps, which is ideal for precise control of Enterprise desktop-based VoIP applications. Easy to manage The industry standard CLI reduces training requirements, and each VCStack appears as one virtual chassis with a single IP address to simplify management. The x900 Layer 3+ switches run the advanced AlliedWare Plus™ Layer 3 Fully Featured Operating System delivering a rich feature set and an industry- standard CLI. Using VCStack allows stacked devices to appear as a single node on the network, greatly simplifying your management. Administrators can choose from a range of secure remote management options including SNMPv3 and SSH. Triggers automatically run user-defined scripts when specified events occur. Loop Protection detects and warns you if a network loop occurs. You can also specify remedial action, such as shutting down the affected ports. Secure Advanced security features protect your network - from the edge to the core. Network Access Control (NAC) NAC allows for unprecedented control over user access to the network, in order to mitigate threats to network infrastructure. The x900 Layer 3+ switches support NAC by using 802.1x port-based authentication in partnership with standards-compliant dynamic VLAN assignment to enable a user’s adherence to the network’s security policies to be assessed and authentication either granted or remediation offered. Allied Telesis NAC also supports alternatives to 802.1x port-based authentication, such as web authentication to enable guest access, and MAC authentication for end points that do not have an 802.1x supplicant. Furthermore, if multiple users share a port then multi-authentication can be used and a Guest VLAN (also known as Default VLAN) can be configured to provide a catch-all for users without an 802.1x supplicant. As well as supporting a RADIUS client for remote authentication, the x900 Layer 3+ switches have a built-in RADIUS server for local authentication. Additional security features include a full RADIUS client and server implementation for remote and local user authentication, Private VLANs to provide port isolation when multiple customer use the same VLAN, and STP Root Guard to protect against an unauthorised device becoming the STP Root Bridge.

A high-availability infrastructure is now of paramount importance, starting with a resilient network core. The Allied Telesis expandable x900 series switches provide the ideal solution - without the expense of a full chassis. With the benefits of high availability, increased capacity and ease of management, VCStack makes networking reliable and simple. Using Virtual Chassis Stacking (VCStack) at the core of your network allows multiple switches to appear as a single virtual chassis. In normal operation, this virtual chassis acts as a single switch, simplifying management. The diagram below shows link aggregation between the core VCStack and the edge switches. With link aggregation across ports on different virtual chassis members, there is no perceptible disruption in the case of a link failure, and the full bandwidth of the network is available. VCStack and link aggregation provide a solution where network resources are spread across the virtual chassis members, ensuring device and path resiliency. Virtualization of the network core ensures access to information when you need it. What's new? Dynamic Host Configuration Protocol (DHCP) Snooping DHCP servers allocate IP addresses to clients, and the switch keeps a record of addresses issued on each port. IP Source Guard checks against this DHCP snooping database to ensure only clients with specific IP and/or MAC address can access the network. DHCP snooping can be combined with other features, like Dynamic ARP Inspection, to increase security in layer 2 switched environments, and also provides a traceable history, which meets the growing legal requirements placed on Service Providers. sFlow sFlow is an industry standard technology for monitoring high speed switched networks. It gives complete visibility into the use of networks enabling performance optimization, accounting/billing for usage, and defence against security threats. Sampled packets sent to a collector ensure it always has a real-time view of network traffic. VCStack Fast Failover Virtual Chassis Stacking (VCStack) delivers resiliency and scalability to networks, simplifying management while increasing performance. Fast Failover further enhances this advanced solution by providing absolutely minimal network downtime in the event of a problem. Strong Passwords Enforcing strong passwords for users of key networking equipment allows network administrators to increase security, and ensure a robust and reliable infrastructure.
